Modal differential substructure method, which can quickly predict effects of structural modifications, has been proposed by the author. This method is a kind of modal synthesis and utilizes dynamic current characteristics of modified structure. The method is convenient because it does not require the user to determine the structure modification beforehand and the user can choose the segmentation after checking dynamic characteristics of current structure. This paper elucidates the difference of formulation between the proposed method and conventional methods. As with other building block approaches, however, the predictions of effects of structural modifications with this method involve errors. In this paper, a technique to reduce those errors is proposed and the method is compared with conventional methods in terms of error reduction effect and computational efficiency.
